Hope someone can give me some advice. I have a Samsung D900i phone which lately give me problems such as I can't hear the person on the other side. It's just breaking up, but at times it appears again, then it just disappear. I have send my phone to a authorized Samsung cellphone repair company which have done the following : Upgrade the Firmware, replace the speaker and the ribbon. (I think that is the ribbon connecting the speaker to the main board?) But still this problem is just happening again. Does anyone experience the same with the D900i or what can be wrong with it?
